"The business-to-consumer (B2C) group is a much newer area and largely
equates to electronic retailing over the Internet. This category has
expanded greatly in the late 1990s with the growth of public access to
the Internet. The business-to-consumer category includes electronic
shopping, information searching (e.g. railway timetables) but also
interactive games delivered over the Internet. Popular items purchased
via electronic retailing are airline tickets, books, computers,
videotapes, and music CDs."
"The business-to-business (B2B) group includes all applications
intended to enable or improve relationships within firms and between
two or more companies. In the past this has largely been based on the
use of private networks and Electronic Data Interchange (EDI).
Examples from the business-business category are the use of the
Internet for searching product catalogues, ordering from suppliers,
receiving invoices and making electronic payments. This category also
includes collaborative design and engineering, and managing the
logistics of supply and delivery."
